FREDERICK GRUMME, OF INDIANAPOLIS, INDIANA;

Application filed October 9, 1911,.Seria1 No. 653,5

To all whom it may concern:

following is a full, clear, and comprehensive specification andexposition, being such as will enable others to make and use the same 7v with absolute exactitude.

drinking fountain which is especially adapt-i ed for use in publicplaces, which will be strong and durable in construction. and not liableto become inoperative through use, abuse, or disuse, which will be neatand attractive in appearance, easily placed in position, whose operationwill be easily understood, which will be easily operated and controlled,and which can be manufactured and sold at acomparatively low price.

A more particular object of this invention is to provide a constructionwhereby the water will form a solid column in suchmanner that a drinkmay be conveniently taken by a person without the use of a cup or otherutensil and without personal contact with any part of the fountainexcept by ones hand, which latter is merely to operate the valve torelease the flow of water and even that may be dispensed with ifpreviously arranged for. And finally a further and more specific objectis to provide a sanitary Artesian like drinking fountain adapted toconserve the use of the water supply by automatically cutting off thewater when the fountain is not in use, and means whereby the flow ofwater may be resumed when desired.

Other objects and particular advantages of my invention will be broughtout in the course of the following specification, and that which is newwill be correlated in the appended claims.

One manner for the carrying out of my invention in a practical way, andthat which in practice I have determined to be the most practical, isshown in the accompanying twosheets of drawings, in which- I Figure lisa plan view of the fountain ready for operation. Fig. 2 is aside'elevation of the fountain showing same as 1n operation. Fig. 3 1s avertlcal sectlon of the wfountain astaken centrally therethrough.

Specification of Letters Patent.

Fig. 4 is a detail view showing. a central section of the centralportion of the device, particularly showing one portion of' the yalve,the parts shown in this View. being 1nverted.' Fig. 5 is a plan: view.looking down onto, and into,-the parts shown in F 1g. 4. Fig. 6 is aside elevation of the valve head. And Fig. 7 is a plan view of the upperface of the valve head.

Similar indices denote like parts throughout the several views of thedrawings. In order that the construction and the operation of inventionmay be more clearly comprehended I will now takeyup a detail descriptionthereof in which I will set forth the invention as fully and as brieflyas I may.

The j body of "the. invention comprises a casing l, which forms acircularvertical 7 wall. Formed integral with the upper portion of thewall 1 and extending downvwardlyand convergently inside the wall 1,

is the bowl 2, which has a bottom 3 integral therewith. The-uppersurface of the bottom 8 is formed convex, but the under face thereof isformed perfectly flat. At the point of union between the bowl and itsbottom there is provided a plurality, of comparatively large exhaustapertures, as for instance those denoted by the letters Patented Sept.1, 19,14. 41. Renewed January 29, 1914. Serial No. 815,288.

y, .2 and c, which are formed through the wall of the bowl and they arepartly in'the bottomthereof.

Extending centerward from about the center (vertically) of the casing 1is a partition 4, which extends downward and centerward at an angle,leaving a large mouth centrally 'therethrough whose edge is interiorlythreaded to receive the disk 5 which is adapted to be secured thereinasshown. The disk 5 has a large central aperture therethrough, fromaround which extends down the comparatively large tube 6 which isintegral with the disk 5. Formed around on the inside of the tube 6,below the center thereof, is therib 7, below which the interior of thetube is threaded, for the purposes stated.

Numeral 8 denotes a nipple which is adapted to freely pass through therib 7,

of the bottom 5 is the resilient disk or cushion 1'1. Formed around onthe upper face of the head 10 1s av rldge or chime a which is adapted tocontact with and press into the disk 11 in order to form a water-.

tight joint. Extending up centrally through the head 10 is the duct 7)through which the water supply may pass when the valve is opened.

Numeral 12 denotes a helical spring whose co nvolutions surround thenipple 8. One end of said spring engages the under edge of the head 10and the other end thereof engages the rib 7, as indicated. The tensionof said spring should be such as to press the head 10 upward withconsiderable force,

causing the ridge a to embed in the disk 11.

Numeral 13 denotes a suitable packing around the nipple 8, below the rib7 and it is adapted to be compressed by the nut 14 so that there will beformed a water-tight joint around the nipple at that point.

Located around inside the flange 9 is a strip 15 which is permanentlysecured to the wall of the flange 9, and it has two diametricallyopposed notches, 0 and e, therein, as shown in Fig. 4.

Surrounding thehead 10 is a strip 16 which has two diametricallyopposite darts, f and f", extending up thereabove which are of the samesize as are the notches e and e,

in which they are adapted to fit when the valve isclosed.

In each of the apertures w, y, and o is secured a conduit which areindicated by the numerals 17, 18, 19 and 20, respectively. The otherends of said conduits pass through and are secured in suitableaperturestherefor in the partition l. The last named aperturescorrespond with the said apertures 00, y, 2 and o.

.Formed around in the upper portion of the bowl 2 are a plurality ofsmall delivery apertures (Z which are so positioned in the angular sidesof the bowl as to direct each a stream of water therethrough, as thestreams h for instance, to a common center.

- When these streams meet withforce at the common center then the forcewith which they meet should be such as to shoot all of the waterdirectly upward forming a geyser cally.

The lower end of the nipple 8 may be connected by the coupling 22, tothe supply pipe 23.

Numeral24 denotes an arrangement for catching the waste water. This maybe a funneldike structure as shown which leads the water down into thewaste pipe 25.

In practice the arrangement of my invention is very simple, and issubstantially as follows: it is of course intended that the nipple S beconnected to the supply pipe which carries the water under pressure.Normally the spring 12 presses the head 10 up against the disk 11 withforce such as to shut off C re water, that is,.preventing the water fromceca ough the duct'b, at which time the dar s -f are fitting in thenotches e e. Now should the handle 21 be pressed slightly to the rightor the left from its normal position, it is evident that this movementwill cause the edges of the darts f f to slide upwardly on the edges ofnotches e-e, thereby forcing the cushion 11 upward a slight distanceaway from disk 11, and against the resiliency of the spring 12. Thislast movement will, of course, allow water under pr re to pass throughthe duct 6, into the s ice above the head 10, then down around the headinto the tube 6. From the tube 6 the water will be forced up 11rdthrough the disk around the flange 9 into the space above the partition4, inside the wall 1, and underneath the bowl 2. The only exit for thewater from said space is through the apertures (Z. The streans from allof said apertures (I will converge in the center as shown in Fig. 2,thereby forming the geyser-like column 70, above referred to. The waternot utilized will fall down into the bowl 2 and. then pass through theseveral conduits into the space below the partition .41, from whichlatter space it will be conducted to the waste-pipe by the funnel 2 f.

From .the above it is evident that the fountain is automatic in closing,thereby conserving the consui'nption of water. However if it should bedesired to have the fountain operate continuously then one has only toremove the spring 12, the cushion 11, and the handle 21.

By reason of the shape of the bottom 3, and the positions of conduits,it is manifest that no water is allowed to stand in the bowl or cup.

The various features and advantages involved in this construction havebeen stated as clearly as possible in or der that the involvedinvention, and its advantages may be readily comprehended even by theinexpert.

I desire that it be understood that my invention is not to be limited tothe precise details of construction herein set forth, but I desire thatit be understood that various changes may be made therein Within thelimits thereof without departing from the spirit of the invention orsacrificing any of the advantages thereof.

Having now fully shown and described my, invention and the best meansfor its construction to me known at this time, what I claim and desireto secure by Letters Patent of the United States, is

1. A sanitary drinking fountain including a bowl having a convex bottom,drainage conduits leading from the bottom of the bowl, there being aplurality of inlet apertures formed in the upper portion of the bowlwhich are adapted to direct streams of water to a central point in suchmanner that the force of the water will cause it to form a solid columnabove the meeting point, a valve adapted to automatically shut off thewater supply, and means whereby if the fountain be turned horizontally aslight distance the valve will permit the water to be discharged throughsaid apertures in the bowl as set forth, all substantially as described.

2. A sanitary drinking fountain including a bowl having a convex bottomand sloping sides, means for draining the bottom of the bowl, a valveadapted to automatically shut off the water supply, means whereby if thedevice be turned slightly the valve will be opened permitting the waterto be admitted into the fountain and to be discharged through aperturesformed in the wall of the bowl in such manner as to cause the severalstreams to meet in a common center and then be forced upward forming asolid column, all substantially as shown and described and for thepurposes set forth.

3. In a sanitary drinking fountain, a stationary supply-pipe, a headhaving a central vertical aperture therethrough secured on the upper endofthe supply pipe, a strip surrounding the head and having a pair ofdiametrically opposite darts extending upward therefrom, an invertedcuplike member, a strip extending around the inside of said member andhaving notches therein in which said darts are adapted to' fit, acushion located in the top of said cup-like member with which said headis adapted to engage, a spring adapted to normally retain said cushionin contact with the face of said head,

vthe whole forming a valve for restraining the water under pressure inthe supply-pipe but allowing it to be released when said cup like memberis turned horizontally in either direction, as set forth.

4:. A sanitary drinking fountain comprising a fixed supply-pipe, a headlocated on the end of said pipe, a movable flange surrounding the head,a bowl, a bottom for the bowl, the underside of said bottom forming thecover for the space inclosed by said flange, a casing surrounding thebowl and spaced therefrom, said casing, bowl, bottom and flange beingformed integral with each other, and the wall of the bowl being formedat an angle with relation to the casing, there being delivery aperturesformed around through the upper portion of the bowl, drainage conduitsleading from the bowl, a partition located below the bowl, a' diskadapted to close the central aperture in said partition, a tubeextending down from said disk and located around the supply pipe, a ribformed around in said tube, a spring surrounding the tube with one endthereof pressing on said rib and the other pressing on the under edge ofsaid head, a cushion against which the face of said head is adapted tobepressed by said spring, and means whereby said head and cushion may bespaced apart, all substantially as shown and described.

In testimony whereof I have hereunto subscribed my name to thisspecification in the presence of two subscribing witnesses.
